What is Windmill?
Windmill hardens for untrusted multi-tenant workloads while sharpening local DX
Windmill is a developer platform for running scripts, flows, and apps, and its recent releases split between enterprise-grade execution hardening and developer ergonomics. The standout is a daemonless, nsjail-sandboxed container runtime that runs arbitrary images without a Docker socket, isolated enough that Docker scripts are now allowed on Windmill Cloud. Around it sit incremental infra wins: smarter Kubernetes scale-in, inbound distributed tracing, remote SSH execution, and audit-log export.
What is Knock?
Knock is pushing its agent into more surfaces while making notification config a no-engineering job.
Knock, a notifications-infrastructure platform, is building two parallel tracks: an agent that can create and manage messaging resources from inside tools like Slack, and a steady stream of dashboard-driven features that move configuration work off engineers. Recent releases span a hosted preference center, dynamic audiences, new data sources, and template tooling. The product is widening from a developer API toward a self-serve control surface.

Windmill hardens for untrusted multi-tenant workloads while sharpening local DX
◆ Current state
Windmill is a developer platform for running scripts, flows, and apps, and its recent releases split between enterprise-grade execution hardening and developer ergonomics. The standout is a daemonless, nsjail-sandboxed container runtime that runs arbitrary images without a Docker socket, isolated enough that Docker scripts are now allowed on Windmill Cloud. Around it sit incremental infra wins: smarter Kubernetes scale-in, inbound distributed tracing, remote SSH execution, and audit-log export.
◆ Where it's heading
The direction is making Windmill safe and observable enough for large multi-tenant and regulated deployments: isolation that needs no privileged daemon, autoscaling that protects running jobs, end-to-end traces, and SIEM-ready audit logs. In parallel, the wmill dev live preview and editor integrations lower the friction of authoring locally. Enterprise hardening and self-serve DX are advancing together rather than one at the other's expense.
◆ Prediction
Expect further isolation and observability work, more sandboxing options and broader tracing coverage, plus continued investment in the local-to-cloud authoring loop.
Knock

Knock is pushing its agent into more surfaces while making notification config a no-engineering job.
◆ Current state
Knock, a notifications-infrastructure platform, is building two parallel tracks: an agent that can create and manage messaging resources from inside tools like Slack, and a steady stream of dashboard-driven features that move configuration work off engineers. Recent releases span a hosted preference center, dynamic audiences, new data sources, and template tooling. The product is widening from a developer API toward a self-serve control surface.
◆ Where it's heading
The direction is toward less engineering involvement per change — agents, dashboard-built audiences, and hosted end-user UI all shorten the code path. Integrations like the Shopify data source extend Knock's triggers into commerce events, broadening what notifications can be driven by. The agent and the dashboard keep absorbing tasks that previously required custom code.
◆ Prediction
The next moves likely deepen the agent (more surfaces or skills) and add further data sources, continuing the shift toward dashboard- and agent-driven configuration over hand-written integration code.
